Abstract
A liquid jet, ejected through a nozzle, is modulated using a drop formation device to cause the jet to form drop pairs, including first and second drops, traveling along a path separated in time on average by a drop pair period. A charging device, synchronized with the formation device, produces first and second charge states on the first and second drops, respectively, using a waveform including a period equal to the drop pair period and first and second distinct voltage states. A relative velocity of first and second drops from a selected drop pair is varied using a velocity modulation device to control whether the first and second drops of the selected drop pair form a combined drop having a third charge state. A deflection device causes the first, second, and combined drops having the first, second, and third charge states to travel along first, second, and third paths, respectively.
